摘要： A clutch connection/disconnection system (1) which causes a friction clutch (8) to slip appropriately when the clutch is automatically disconnected and connected. An engine is controlled according an accelerate command signal. During automatic clutch connection, the accelerate command signal approaches an actual accelerator pedal position signal. An approaching speed of the accelerate command signal is stepwise changed based on comparison between a particular value (S) and a threshold value (H1, H2). The "particular value" is a differential value (S) of a difference between an engine rotational speed (Ne) and clutch rotational speed (Nc). When the clutch is slipping, the engine rotational speed is controlled to rise gently so that overslipping of the clutch is prevented.

摘要： The clutch disengagement and engagement device (1) comprises an automatic clutch disengagement and engagement device or an automatic clutch disengagement and engagement device (2-79) for automatically disengaging and engaging a clutch 98) upon receiving a specified signal. The device (1) furthermore comprises an engine control device (open or closed loop) or an engine control device (open or closed loop) to control an engine (91) of a car according to an acceleration command signal which is generally different from an actual acceleration or gas pedal position signal, when an automatic disengagement and engagement of the clutch is undertaken. The acceleration command signal approaches the actual acceleration or gas pedal signal when an automatic engagement of the clutch is undertaken and a, or the, approach speed of the signal to the actual acceleration or gas pedal signal, based on one or more parameters, determines which parameters comprise at least one of the following: motor revs, actual acceleration or gas pedal position, gearbox position of a, or the, transmission, car travel speed, acceleration or gas pedal depression speed and reduction gear ratio or reduction ratio of the gearbox of the car.

摘要： The neutral position of a control device for a flow rate control valve is accurately learned by means of a simple configuration. The control device for a flow rate control valve is provided with an actuator (12); an operation fluid supply source (11); a stroke sensor (14); a flow rate control valve (15) which comprises a valve element (19) and is provided with a supply unit (17a) communicating with the operation fluid supply source (11), a discharge unit (18a) discharging operation fluid, and a communication unit (16a) communicating with the actuator (12); and a control unit (20) which controls the valve element (19) according to values detected by the stroke sensor (14). The control unit (20) comprises a neutral position learning unit (22) wherein the movement amount of the valve element (19) that corresponds to the neutral position thereof is leaned from the movement amount of the valve element (19) at the time when it is determined from a value detected by the stroke sensor (14) that the valve element (19) is in the neutral position whereat the communication unit (16a) is blocked after the valve element (19) moves from the location of the discharge unit (18a), and from the movement amount of the valve element (19) at the time when it is determined that the valve element (19) is in the neutral position whereat the communication unit (16a) is blocked after the valve element (19) moves from the location of the supply unit (17a).

摘要： A clutch control device for a vehicle, provided with a clutch actuator driven by an operating fluid. Secular changes of a flow rate control valve for controlling the operating fluid is compensated, and the amount of engagement of a clutch can be accurately controlled by a simple means. A clutch control device comprises, in order to control the stroke of a clutch actuator (110), a single flow rate control valve (1) for controlling supply and discharge of an operating fluid by means of an electromagnetic solenoid. A flow rate control valve controlling device (9) is provided with a learning device (91) for learning the neutral position of the flow rate control valve (1) which blocks the flow of the operating fluid. The learning device (91) detects, for each direction of movement of a valve element of the flow rate control valve (1), the amount of electric current conduction to a coil (8) when the speed of a change in the stroke is zero, and then the learning device (91) averages the detected values to learn the center point of the neutral position. In stroke control of the clutch, the amount of conduction of an electric current to a coil (8) is corrected on the basis of the learned value to compensate a change in flow rate characteristics caused by secular changes.
